Latest studies indicate that RZV (Recombinant Zoster Vaccine) (*Shingrix®), a non-live vaccine, was able to reduce dementia risk by up to 13% in men and up to 22% in women aged 65 and above when compared to *Zostavax ( a live Zoster vaccine), 6 years post vaccination.
The risk of dementia in those who got a *Shingrix shot was 23% lower than in people who got an influenza vaccination and 28% lower in people who got a tDAP (tetanus, diphtheria and *PERTUSSIS) vaccination.
p/s:
*Shingrix and *Zostavax are vaccines to reduce risk of Shingles infection, also known as Ular or 蛇(Shé). Zostavax vaccine has exited Singapore since December 2024. Only Shingrix is available in Singapore.
*PERTUSSIS bacteria causes 100 days cough. tDAP vaccination reduces 100 day cough infection risk.
A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20% — more than any other known intervention.
